I would forget about about your roth IRA and clear your debts. Interest rates at the minute are low so now is the time to get clear of debts. When you clear your debts you can save in the future, especially since you have a good salary. I would concentrate on paying the credit cards first, as you have said you could clear them in a year. Getting totally clear of one debt is much better than trying to pay several at one time. Alternatively you could go for loan consolidation and combine all your debts.
If you want to keep your car with negative equity why don't you sell the other car you bought for $4500, this could be an extra $4500 to help you pay your credit card debt and other auto. By selling this and stopping roth ira payments you would have an extra $9300 this year which would pay a good part of your credit card debts. Then you can focus on paying your auto back. Once you ahve your auto paid back you can then think about reopening your roth ira and saving again.
